Dear all,

Next week the Horowitz seminar will hold its final meeting for the
semester. We are happy to have:

Speaker: Piotr Milos, University of Bath and University of Warsaw
Title: Heavy-tailed branching Lévy motion in inhomogeneous potential

Date: Monday, January 21
Time: 14:30
Place: Schreiber 309

Abstract:
In my talk I will present results concerning a branching system as
follows. Particles evolve according to a real-valued Lévy motion
with heavy tails and branch according to a dyadic branching law. We
consider three different regimes of the branching rate:
- constant in space, then the system size grows exponentially.
- \beta \log(x), then the system size grows as exp(exp(\beta/(e
\alpha)t)).
- \log^{1+\epsilon}(x), then almost surely the system explodes, i.e.
produces an infinite number of particles in finite time.
These are joint results with Simon Harris (University of Bath)

Have a good semester end!
Ron
